Title: Tape cartridge
Inventor: SOGABE TERUO
IPC: G11B23/087
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent a reel stopper and a spring which are assembled in advance on a lower case, from jumping out to the outside of a case by the exerted external vibration, etc., in the process of the assemblage in a tape cartridge provided with the compression coil spring and the reel stopper energized with pressurization to the direction of the lock position by this spring. SOLUTION: The spring 14 is arranged between a spring receiving surface 21 of the reel stopper 10 and a rear wall 9 of the case confronted with the spring receiving surface 21. The advancing limit position is settled to the stopper position at the time when a tape reel 3 is held for locking by the reel stopper 10. By making the confronted space between the spring receiving surface 21 and the rear wall 9 of the case at this limit position to the reference dimension, the free length L of the spring 14 is set to the same as the reference dimension. Thus, the exertion of the spring force on the reel stopper 10 is prevented at the advancing limit position, then the jumping out of the reel stopper 10 to the outside of the case is eliminated.

Title: Copper clad board
Inventor: ARAI MASAMI
IPC: B32B15/08
Filed: 1989-08-04
Abstract: PURPOSE:To prevent virtually the generation of dimensional change induced by etching and its post heating by installing a resin layer which contains a specific amount of filler on an inner surface which faces a copper foil. CONSTITUTION:A copper foil 1 is laminated on both sides of a resin-impregnated base material which comprises cotton cloth impregnated with resin by way of a filler-impregnated resin layer 2. The cotton cloth 3 to be used comprises inorganic and organic fiber textile, such as glass fibers, polyamide fibers. Resin 4 is thermal plastic resin, such as epoxy resin and polyamide resin. A filler is an inorganic filler, such as aluminum hydroxide, silica powder, mica or inorganic fiber, such as glass fiber, potassium titanic acid fiber. The thickness of a filler-impregnated resin layer 2 is 10mum or more, preferably it is 30mum or more. The content of resin for the filler-impregnated resin layer is usually selected from the range between 20 to 80 weight percentage. However, selection of the range of resin content smaller than that of a laminated board comprising the cotton cloth 3 and the resin 4 is more preferable to inhibit dimensional change.

IPC: G11B7/14
Filed: 1994-08-30
Abstract: PURPOSE: To relieve restriction on a power supply voltage by the forward voltage drop of a laser by enabling driving of the laser with the low power supply voltage. CONSTITUTION: This laser driving circuit is composed of the laser 101 having a light emission central wavelength of <=630nm, a constant current circuit 105, a current changeover means 103 connected in series to this constant current circuit and an inductor 104 connected in series to the constant current circuit. A pulse voltage is otherwise generated in the inductor by passing pulse current to the indicator by a high-frequency current generating means and the current from this inductor is added to a laser driving current. The need for preparing a power source of a high voltage for laser driving or a special boosting means is eliminated by driving by the power supply voltage of <=5V. The lower electric power consumption and the smaller size and lower cost of the device are thus resulted.
